The enhanced electron fluxes (from the solar wind and/or photoelectrons) considered in the current paper could explain the enhanced H I , O I , and C I emissions from dissociation of H 2 O and CO 2 observed by the Alice (Rosetta's UV imaging spectrograph) instrument, as discussed by, This would make a good future project, 1978. ,
